IOS Zombie shooter Infected Wars has launched on Vita Last month in the US and hopes are high on a UK/Europe version soon.
Developers have said they'd love to but sales of the game in the US may dictate if that is to happen. At only $4.99 I'd like to think that many US Vita owners will give it a try.

For gamers like myself that need inverted controls, or it's a game breaker will be pleased to here that the developers plan to update with inverted controls soon.
